Energy storage is a particularly effective way to increase your energy autonomy. During the summer, daytime power production often exceeds the demand at any given time. In a standard installation, the excess is sent to the grid and the prosumer can collect it later. However, the grid owner takes 20–30% of the energy received. Whereas installations equipped with an energy storage system, redirect the electricity straight to the batteries, and the installation owner does not lose any kilowatts produced.

Owners of inverters with UPS or ESS function are also protected against power outages. The inverter will switch to emergency power mode and begin drawing power from the charged batteries. The prosumer will therefore be able to use electrical appliances despite the lack of electricity in the area.

Achieving full energy independence under current technical conditions is justified in places where there is no power grid. The optimal solution is to increase self-consumption in on-grid installations by using batteries.

The first step is to determine energy requirements. To do this, the prosumer should contact their installer or an advisor and analyse electricity bills from recent years as well as additional needs, such as  protection against power outages.

In its simplest form, a PV system with energy storage consists of a hybrid inverter and a size- and type-matched energy storage system in the form of a battery. Other components of the PV system are the same as in a typical installation. A major difference is the need for the space to install the battery.

The Victron MultiPlus inverter, unlike many hybrid inverters, offers the ability to connect to an existing PV installation. It is a perfect solution for those who want to expand their installation with an energy storage system that has a UPS function.

Yes, in most cases the cables to connect to the inverter are included.
